Experimental identification of multimode traveling waves in a coupled wave-tube
Yoav Vered, Izhak Bucher
An essential part of nondestructive testing and experimental modeling of waveguides is the decomposition of propagating wave patterns. The traveling wave ratio is a measure of part…
A new approach to single-tone frequency estimation via linear least squares curve fitting
Solomon Davis, Izhak Bucher
Presented is a new algorithm for estimating the frequency of a single-tone noisy signal using linear least squares (LLS). Frequency estimation is a nonlinear problem, and typically…
Balancing rotating structures using slow-speed data via optimized parametric excitation and nonlinear feedback
Amit Dolev, Shachar Tresser, Izhak Bucher
The paper presents an improved mass balancing procedure for fast rotating machinery, while it is being rotated at speeds considerably slower than the "critical speeds", where dange…
Analytical, numerical and experimental investigation of a tunable, nonlinear multi-degree-of-freedom parametrically excited amplifier
Amit Dolev, Izhak Bucher
A tunable, multi-degree-of-freedom, parametrically excited amplifier is introduced as an apparatus capable of shifting slow, weak signals to higher frequencies, by exploiting the a…
Optimizing the dynamical behavior of a dual frequency parametric amplifier with quadratic and cubic nonlinearities
Amit Dolev, Izhak Bucher
The paper describes a novel parametric excitation scheme that acts as a tunable amplifier by controlling two pumping signals and two nonlinear feedback terms. By modulating the sti…
Realization of a Contactless Acoustic Levitation Motor via Doublet Mode Control and Autoresonance
Solomon Davis, Izhak Bucher
This paper demonstrates analytically and experimentally an acoustic levitation motor which has the ability to levitate and rotate an object in the air without mechanical contact. T…
